The relay's primary winding is supplied from the power systems current transformer via a plug bridge, which is called the plug setting multiplier ( psm ).

Like any transformer, a current transformer has a primary winding, a core and a secondary winding, although some transformers, including current transformers, use an air core.
43.
Then you say it is a Hall Effect sensor, which is not a current transformer, but which could be connected to the secondary of a current transformer.

The main control substation at Woolloongabba supplied power at 11kV, which was stepped down to 5kV at Coorparoo, and fed to a bank of constant current transformers.
45.
Five of the nation's 18 nuclear power plants were closed because their main current transformers or power lines were damaged by the typhoon, the anti-disaster headquarters said.
46.
His work at PTB primarily dealt with high voltage / high current research and development, and in 1914 he developed a measurement methodology for examining current transformers.
47.
Then you say it is a Hall Effect sensor, which is not a current transformer, but which could be connected to the secondary of a current transformer.
48.
Current transformers used for protective relaying also have accuracy requirements at overload currents in excess of the normal rating to ensure accurate performance of relays during system faults.
49.
A neutral current transformer is used as earth fault protection to measure any fault current flowing through the neutral line from the wye neutral point of a transformer.
50.
A common Direct Current power plug is intended to make life easier by eliminating the confusion regarding what voltage and current transformer one needs to buy and carry.
